' consequently turned to closed position, as

indicated in dotted.- lines in l igrure 4.

In order to prevent the opening of the valve by the remote control means, hereinafter described, atter it has been turned to closed position and the burner consequently extinguished, a dog; 16 is pivotally mounted 011 the upper end of the stop 14, and is adapted to be swung to the dotted line posi .tion shown in Figure 4 into contact with .the base ot the finger (3, and thuszetleo ur .ally guards against the slightest openin movement of the valve. It will. be apparent that when it is desired to open the valve, the operator must manually rotate the dog 16 toils inoperative position.

it is sometimes des ble to regulate .the size of the fiameby means of a remote control in an upstairs room for example the reduced end 7 of the valve stem is received within the bore'ot a coupling 17 and is held fixedly in position by means of a set screw 18. Received in the opposite end of the coupling, is the end of extension rod 19 held in position by a second set screw 20. The-upper end otthe rod preferably passes through an opening; 21 in the floor 22 of one of the rooms of the building and has abeariug in an opening formed in an-inverted strap bridge member 23 proiecting downwardly into the opening 21. The bridoe member forms a part of an indicatingdisk'24lprovided with indieatins; numerals 25 arranged in a manner similar to the numhersot the plate 8 and coincidental therewith, and said disk is held in position by means of suitable screws 26 or the like, in engagement: with thefioor 22. It will be evident that, it desiredxthe disk 24- may be located on a bracket or the like projecting from onset the walls of the roomiinstead of being mounted on thex floor.

If the device is mounted in the loor, the top of the rod 19 will-be cut oli tluslrwith the top of the floor, and. said rod will-be flattenedslinjhtly as at 27 on one of its sides for engagement with similar shaped opening! formed in a' tubular. key .member 28 having a combined oneratinpgand indi cat-inn finger 29- t'or registering. with the indicating numbers of the plate ordisk 24.

In! this connection it willbe apparent that dueto the flattening-.otthe rod. at one of its sides, it will-be necessary that the kev shall. always he applied in thesame posi- Byhavinq a removable key. the likelihood tl at childnenwill tamper. withithe setting of the valve is obviated. It will be evident that by forming the upper bearing for the extinguisament of the llan'ie or th tloodin rod in. the shape of an inverted strap arch, a pair of over- 23 are provided at opposite sides of the rod, through which dirt and refuse accidentally swept into the device will he tree to tall to the floor of the cellar and will not clog: or intertere with the proper operation of the remote control.

By the use of the control pins or stops above described, it will be apparent that a sate working range for the operation oi the burner is provided and that the accidental ot the burner by the use of the ren'iote control are obviated.

From the above description it will be ap parent that I have produced a device ol the character described which possesses all the teatures of advantage set torth as desirable; and while I have described and claimed the preferred embodiment of the same, I reserve the right to make all changes properly talling within the spirit and scope of the appended claims.

I claim:

1. In an apparatus of the eharmrter described, a valve, a plurality ot corresponding dials, one of which is adapted to fit the stem of the valve andthe otherheing securedin a remote position, variable stop means for limiting the movement of said valve stem, a rod adapted to pass through the remote dial and form a rigid conneotion with. said valve stem, and means for turn 'ing the rod at the remote dial.

In an apparatus of the character described, a valve, a dial adapted to-fit the stem of the valve, means for holding the dial in fixed position, variable stop means for limiting the movement; of said valve -w.ith said valve stem, and means for turning the rod at the remote dial.

4:. In apparatus of the character described, a valve, a marked dial axially alined with. the stem of the valve and provided with an extension engaging the valve to fix th position of the. dial. a second dial having; markings co responding to the marks of the first dial. a rod secured to the valve stem and engaging;- the second dial, and an indicator tor engagement with the rod to turn the same with reference-to the marks ont-he second dial.

5. In apparatus of the character described, a valve, a rod coupled at its lower end to the stem ofthe valve, a dial secured to a floor and provided with a depending bridge engaging an opening in the floor and forming a journal for the upper end of the rod, and an indicator for extending radially of the valve and provided With a hub extending through the dial above the bridge, the hub and rod having detachable but rigid relation as regards turning movement.

6. In apparatus of the character described, a valve having an indicating arm attached to the valve stem, a dial, and a stop pin normally in the path of travel of said indicating arm, said pin being yieldinglyactuated to permit said arm to pass beyond the pin.

7. In a device of the character described,

20 a valve having an indicating arm attached limit the closing movement of the valve,-

said second pin being yieldingly-actuated to permit the indicating arm to pass beyond the pin to closed position, and a latch for holding the valve in closed position.

In Witness whereof I hereunto aflix my signature.
